Data Wrangling
Geospatial
In order to calculate percent protected by watershed, I used spatial intersection to find the overlap between the protected areas in the CPAD database and each monitored watershed. I then divided the total area of overlap by the total watershed area and multiplied by 100 to find the % protected. I removed any protected areas established after 2009, as this was the first year of data I included in my analysis.
